Scientists note Astronomy That the stars "Dancing" Around Black hole The giant, they recorded and classified infrared bursts and found unknown strange astronomical bodies and objects orbiting around the hole.

According to a new study, it was published in magazine messages Physics Astronomer, Japanese astronomers have studied "Sagittarius A *" by "Atacama Matrix Large Observatory Matrix", Which is a group of radio monitoring devices in the Atacama Desert, northern Chile.

The researchers had previously discovered a massive black hole about 4 million times larger than our Sun at the center "Sagittarius A *"And it emits flashes, which scientists have not yet been able to explain, according to a website "CNet" the meaning With scientific news.

The team of Japanese scientists from the Japanese University of Kyo tracked and focused on the giant black hole for 10 days, in an attempt to monitor the smallest changes in the flash of that cosmic monster.

Keio University astrophysicist and study author, Yohei Iwata, said in a press release "This time, using the observatory, we obtained very accurate data for changes in the intensity of radio waves from (Sagittarius A *), for a period of 70 minutes over a period of 10 days. This happened in 2017, and when the team of scientists studied these data, they found that the giant black hole It flashes regularly".

Co-author Tomoharu Oka added these flashes "It may be related to some strange phenomena occurring near the massive black hole".

Japanese astronomers suspect that this activity may be related to"Cumulative disk", A type of rotating stellar disk consisting of a belt of gas and cosmic dust surrounding the black hole.

Astronomers believe that the flickering signal relates to the inner edge of the cumulative disk of the massive black hole in "Sagittarius A *"And spinning around the black hole at speeds close to the speed of light, and during this process hot spots appear that emit the so-called "Light millimeter and below millimeter", Which is the signal discovered by scientists, and the flash amplifies as hotspots move toward us in space.

There is an opportunity that this activity may tell us more about the behavior of black holes and how gases accumulate around its center.

It is indicated that "Sagittarius A *"It is a shiny region and a very strong radio source, located in the center of the Milky Way, which is part of a larger region called "Sagittarius A.", And contains a huge black hole, as well as the family of black invisible holes.

The black hole in the center of the Sagittarius is about 26,000 light-years away from Earth and does not pose a direct threat to the blue planet.

Astronomers have observed that stars “dance” around the giant black hole, recording and classifying bursts of infrared radiation and finding strange, unknown astronomical bodies and objects orbiting the hole.

According to a new study, published in the letters of the Astrophysical Journal, Japanese astronomers have studied the “Sagittarius A *” by “Atacama Large Millimetric Observatory Matrix”, a set of radio monitoring devices in the Atacama desert north of Chile.

The researchers discovered earlier that there is a massive black hole about 4 million times larger than our sun at the center of the “Sagittarius A *”, and it emits flashes that scientists have not yet been able to explain, according to the website “CNet” on scientific news.

It is noteworthy that “Sagittarius A *”, which is a bright region and a very strong radio source, is located in the center of the Milky Way, which is part of a larger region called “Sagittarius A”, and it contains a huge black hole, as well as a family of holes Invisible black.

The black hole in the center of the Sagittarius is about 26,000 light-years away from Earth and does not pose a direct threat to the blue planet.
